Best ResponseYou've already chosen the best response.1The intersecting lines form an angle. When those lines touch the sides of the circle, they form an arc. That arc has the same central angle within the circle as the angle of intersecting lines.

Best ResponseYou've already chosen the best response.1In other words: if the angle of intersection is in radians, the arc length is Radius * Angle
